Introduction
Please read this entire manual before commencing your
installation.
The Ultra*Stereo XTD-680 is a digital crossover card for use with a CM
series Crossover Monitor Chassis and may provide either three channels
(Left, Center, Right) or, with the addition of a piggyback board, two additional
channels (Left Center, Right Center) of Biamp or Triamp crossover capability.
Subwoofer control is also provided. The card is configured for individual
requirements by an easy to use Graphical User Interface that runs on a
laptop computer communicating via a USB cable. A library of existing
speaker types is provided or each of the features may be configured
manually. Cinema Profile information may be entered for future reference.
Additionally, the XTD-680 is designed to interface with Ultra Stereo's JSD-
80 for complete system equalization.
As
a result, only the Bypass features need to be configured on the XTD-
680 card itself. A DIP switch selects the type of Bypass crossover
(Triamp/Biamp/Biamp Frequency) and three potentiometers set the Bypass
crossover levels. In use, there is only a two position switch for selecting
"Normal" or "Bypass" operation.
